摘要： Disclosed is a method for removing cross-talk in a wavelength division multiplexed passive optical network (WDM-PON). The WDM-PON and the method remove cross-talk between adjacent wavelength channels due to incomplete alignment of wavelength channels in a MUX/de-MUX between a central office and a remote node in the WDM-PON employing light-injected light sources. The WDM-PON includes at least two broadband light sources having different bands, which provide injection light to be injected to light-injected channels light sources, a transmitter receiving injection from the broadband light sources, injecting the injection light to odd channel light-injected light sources and even channel light-injected light sources, arraying odd and even channels in such a manner that the odd and even channels belong to different spectrum bands, multiplexing the signal according channels, and transmitting the multiplexed signal. The WDM-PON may also include a receiver for receiving the multiplexed signal transmitted from the transmitter and splitting the multiplexed signal according to the odd and even channels.

摘要： Disclosed is an IP-based broadcast service system capable of reducing the channel zapping or changing time and the waste of bandwidths during frequent channel changes such as channel surfing. A broadcast server for providing broadcast services generates both high-quality broadcast data and low-quality broadcast data of each TV channel. The broadcast server provides the low-quality broadcast data during a simple channel surfing. When a viewer selects a channel to view, the broadcast server then provides the high-quality broadcast data of the selected channel.

摘要： A system having a transmitter and a receiver provides sign language video data in a broadcasting-communication convergence system. A transmitter extracts data, to which a sign language is to be applied, from the multimedia data, converts the extracted data into motion data, converts the motion data into an avatar motion schema indicative of avatar motion data, converts the avatar motion schema into metadata, multiplexes the multimedia data and the metadata, and transmits the multiplexed data. A receiver receives the multiplexed data, demultiplexes the received multiplexed data, extracts an avatar motion schema using the metadata, generates sign language video data by controlling a motion of an avatar through the avatar motion schema, multiplexes the sign language video data and the multimedia data, and transmits the multiplexed data to a display unit.

摘要： A solution for allowing conditional access to IP-based broadcast services in a passive optical network is disclosed. When a subscriber requests broadcast services by selecting a broadcast channel, an IP set-top converts the request into an IGMP join message and forwards the message to an ONU/ONT, a unit on the subscriber's side. The ONU/ONT delivers the message to an OLT interworking with a router while storing mapping information of the port that received the message and a MAC address of the selected channel. Thereafter, the OLT extracts information on MAC address of the IP set-top box and the requested broadcast data. The OLT compares the extracted information to the subscriber's subscription information and determines whether to provide the requested broadcast services. If the broadcast services may be provided, the broadcast data provided from the broadcast server is transmitted to the IP set-top box via ONU/ONT based on the stored mapping information.
